The other day my sister decided to get a new computer, and because of the art stuff that she does, and the fact there was a relativly cheap Tablet on Trademe, she got one.

The first day was great, but at about 11pm last night, it went really weird. so I went to bed and figured it might sort itself out on its own. Turned it on this morning and it was going fine. (possible over heating)

So its been used heaps today installing new programs and using it as a basic computer and all that. Just now though, it has started doing its weird issues. What happens is that even during the HP BIOS screen, and then in the safe mode screen and throughout the entire computer, it has fuxxy vertical lines allover the screen, about every 5mm. Ocaisionally it will additionally have red squares allover the screen.

Any suggestions on what could be causing this? and what could be done to fix it?

I have the latest drivers installed from HP.

The resolution defaults to the lowest, and to 4bits, even changing it to the highest (what it is at normally) and 32 bit doesnt change it.
